Claims.

' This invention relates to closures for barrels of the type more or less commonly known as full open top in which the head or cover is secured to the top of the barrel by means of a clamping ring, and is particularly directed to the construction of such clamping ring and means for operating the same.

Heretofore split rings have been proposed or used, such rings having links and levers for drawing the ends together but these have been found objectionable for various reasons. For instance the rings are often stuck to the barrel on account of adhesive material which may collect thereon when the barrel is filled with such material. Or in some instances the rings and adjacent portions of the barrel may become jammed in shipthat it makes it difficult to remove the When the ends of the rings are permaas by means of rings it is only a relatively slight opening between the ends of the rings so that it is diflicult to release the entire ring from the head.

In accordance with the present invention I provide closing or fastening means which does not make a permanent connection between the ends of the rings but which may be released so that the ring may be freely sprung open either for the purpose of placing the same on the barrel or removing the same therefrom.

Other objects of this invention are to provide an improved closing ring which may be readily constructed and which may be particularly durnently connected possible to permit able and eflicient in operation; to provide a bar-- rel closing ring having a closing arm or arms detachably connected with one portion of the ring; to provide a ring of this character with closing and fastening device which will also serve for forcing the ring open; and to provide such other advantages and improvements as will appear from the following description with the accompanying drawing-in which Figure 1 is a plan view of a barrel with my improved closure applied thereto;

Figure 2 is an enlarged detail of the double acting, or combined closing and opening mechanism;

These brackets serve to: carry and cooperate with the closing mechanism and extend inwardly and of the closing mechanism extend above the upper surface of the ring.

downwardly so that no parts This is an important feature as it facilitates the handling and stacking of the barrels. The bracket 13. has a 16 at its inner end 1'? which is pivotally secured operating lever thereto by a pivot as shown in Figure bifurcated bearing for receiving one end of an 18. This lever is bent to conbarrel head held in fastening position by means of any suitable catch 19 secured to the ring '11.

The inner portion of the bracket 14 is bent downwardly or offset as shown in Figure 3, in order to bring it in substantial horizontal align- 40 ment with the lever 1'7.

The inner end of this bracket is provided with an irregularly shaped recess or opening 20 The lever 1'! is provided with a double purpose or combined pulling and pushing arm which coacts with the bracket 14 for drawing the ring to closing position and also for forcing the ring open. In the particular form shown formed of two bar at 23 to the lever portions spread to straddle the bearing at The' outer or bracket 13. are connected by a ed to engage with or offset as shown this arm is s 21 and 22 which are pivoted and which have their" central in Figure 3 the inner end'of' the free ends of the bars pin or rivet 24 which is adaptthe. hook-like end or recess 20 of the bracket 14. One side 25 of the recess 20 is curved to form a bearing for receiving the pin 24 for the closing operation. The recess preferably extends outwardly and has another bearing portion 26 for receiving the pin for the loosening or opening operation. The bracket may also have a further notch 27 at its inner end for receiving the pin for spreading the ends of the ring still further apart.

When the ring is to be applied the pin 24 is disengaged-from the bracket 14 leaving the ends free so that they may be spread apart to permit the ready application of the ring to the barrel cover and bead as shown in Figure 4. During this movement the plate 12 serves as a stop as shown in Figure 5, to prevent the ring from falling down over the flange and thus expedites the application of the ring to the barrel. When the ring has been placed in position the lever 17 is swung forwardly so that the pin 24 may be brought into engagement with the bearing 25 in the bracket 14. Then by swinging the lever outwardly or to closing position as shown in Figure 1, the ends are drawn together and the cover is pressed closely to closing position. When the lever is swung to its extreme position it may be fastened by the catch 19.

When the cover is to be removed the lever 17 is again swung forwardly as indicated by the dotted lines in Figure 2 and the pin 24 will engage with the bearing 26 to force the corresponding end of the ring outwardly and thus to release the same. Ordinarily this initial releasing movement will be suificient and the pin may be moved out of engagement with the recess which will permit the operator to grasp the ends of the ring and pull it off from the barrel. However if the initial spreading movement is not sufiicient the pin may be moved out of the recess 20 and brought into engagement with the outer portion of the bracket, and another movement of the lever will cause the furtherspreading of the ends of the ring. As above suggested this provision for opening the ring is of particular importance where the ring has been stuck on as by paint or the like, or has been jammed in transportation so that it is difiicult to remove the same.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A new-article of manufacture comprising a split closing ring for barrels having a bracket extending inwardly at one end of the ring, a bifurcated bearing at the inner end of the bracket, a lever having one end pivoted in said bearing, a second bracket adjacent to the other end of the posite ends of said arms,

ring having a recess at the inner end thereof, bars pivoted to the lever at a short distance from said bearing, said bars being offset to straddle the bearing, and a pin bars second bracket.

2. A split closing ring of the character set forth having upper and lower faces and having an inwardly projecting bearing adjacent to one end thereof, a lever pivoted to said bearing and adapted to swing in a plane parallel to the face of the ring, an arm pivoted to the lever and adapted to project beyond the bearing, a bracket on the opposite end of the ring having a recess at its inner end, and means on the arm for engaging with 'the recess, the walls of said recess providing oppositely disposed abutments serving to retain said last mentioned means in said recess during contraction and expansion of the ring, and no part of such operating devices extend above or below the upper or lower faces of the ring.

3. A split contractible barrel closing ring in the form of a channel opening inwardly towards the plane of the ring, means coacting with the ends of the ring for contracting the same, said ring having a ledge extending inwardly from the upper edge thereof, and positioned substantially on the opposite side of the ring from the contracting means and serving as a stop when placing the ring in position.

4. The combination with a split closing ring for a barrel, of brackets secured to the ends of the ring and extending inwardly and downwardiy, a closing lever pivoted to one of said brackets, said lever being curved to conform to the inner curvature of the cover, parallel arms pivoted at one end to said lever, a pin connecting the opsaid pin being adapted to engagev with a recess in the second named bracket for the purposes described.

5. The combination with a metallic receptacle having a bead rolled about its open end, and a removable cover for said receptacle having a marginal flange fitting over the said bead, of a split contractible channeled clamping ring having wallsengageable with the flange and bead for pressing the same together when the ring is contracted, inwardly extending lugs adjacent the ends of said ring, a lever for contracting said ring pivoted to one of said lugs, the other of said lugs having a notch therein, a link pivoted to the lever and carrying a pin. at its other end for engagement with said notch.
